• Gather context (read changesets, changelogs)
• Analyze source code to confirm breaking vs. additive changes
• Post summary

Breaking changes in this 0.6.0 release

1. Self-closing childless tags — <0></0> → <0/> (yes, this one's real, but scoped)

• packages/config/src/features/messages/convert.ts:19-27: an element with zero children now compiles to <0/> instead of <0></0>. Elements that have children still emit the paired form — only genuinely-empty elements (e.g. <img />, <br /> inside <Say>) change shape.
• Impact: any already-translated catalog entry (PO/JSON) for a message containing a childless tag won't match the new source string anymore — those specific entries re-extract as new/untranslated and need to be redone by translators. Not a runtime crash, but a catalog-content break worth flagging in release notes.

2. Duplicate placeholder names now throw at build time (new)

• packages/config/src/features/messages/identifier.ts:60-105. Previously, two different values sharing a placeholder name were never checked and silently coexisted (JS's last-key-wins). Now any two non-identical values sharing a name throw Duplicate placeholder name '...' during compilation.
• Impact: code that previously built successfully (while silently dropping one of the colliding values) will now fail the build. This is the other change worth calling out — it can break existing CI builds, not just runtime behavior.

Not breaking (additive / internal-only)

• say-tag attribute (transform-jsx/src/parser.ts:180-209) — new opt-in JSX attribute to name placeholders; untagged elements keep the old auto-incrementing numeric ids, so default behavior is unchanged.
• Values compiled behind an underscore (transform-js/src/generator.ts:24-26, transform-jsx/src/generator.ts:32-34) — only changes the internal compiled .call()/<Say> prop names (_name instead of name); the runtime (integration/src/runtime.ts:15-22) strips the underscore back off, and the ICU placeholder in the catalog string is still {name}. Existing catalogs and hand-written calls are unaffected.
• Single-key-object placeholder naming ${{ cartTotal: getTotal() }} (transform-js/src/parser.ts:145-169) — purely additive; only matches object literals with exactly one key, so existing expressions like ${getTotal()} compile exactly as before.
• SayProvider rebuild on locale/messages change (integration-react/src/runtime/client.ts:9,24-31) — bugfix (useState → useMemo), same props/signature.
• JSX message source references — additive #: file:line metadata in PO output only.

Summary

Two things worth a release note: the self-closing tag shape change (may drop some existing translations back to untranslated) and the new duplicate-placeholder-name build error (may break builds that previously compiled despite a name collision). Everything else this release is additive or internal.
